  • AD Alzheimer's disease
  • a progressive neurodegenerative disorder is the leading cause of dementia in the elderly population. People progressing to AD develop distressing changes in memory, thought, function, and behavior, which worsen over time. These changes increasingly impact the person's daily life and reduce their independence until ultimately these patients are entirely dependent on others (Querfurth and LaFerla, 2010). Worldwide, it is estimated that about 50 million people have dementia and, every year, there are nearly 10 million new cases. Alzheimer’s disease accounts for 60% to 70% of these patients (who.int/news-room/fact-sheets/detail/dementia - 1 dated September 21, 2020).
  • AD symptoms include impairment of delayed recall, memory loss and problems with concentration.
  • moderate, middle stage which represents the longest stage, symptoms may include trouble remembering events, difficulty engaging in successful problem-solving thought and action, impulsive behavior, shortened attention span, language difficulties, and potential restlessness and/or agitation.
  • severe, late stage patients cannot communicate and are completely reliant on others for their care.
  • AD is inexorably progressive and fatal within 5 to 10 years.
  • AD amyloid b-protein
  • AD amyloid b-protein
  • Other theories include tau, apolipoprotein E (apoE)/lipids/lipoprotein receptors, neurotransmitter receptors, neurogenesis, inflammation, oxidative stress, cell death, proteostasis/proteinopathies, metabolism/bioenergetics, vasculature, growth factors/hormones, synaptic plasticity/neuroprotection, and epigenetics.
  • AD patients Presence of abnormal tau protein, mitochondrial dysfunction, and protein hyperphosphorylation all have been demonstrated in neural tissues of AD patients. Moreover, AD patients exhibit severe sleep/wake disturbances and insomnia and these are associated with more rapid cognitive decline and memory impairment. The costs of AD are accelerating — rising from $1 trillion globally in 2018 to a projected $2 trillion in 2030. Means of preventing, delaying the onset, slowing the progression, and improving the symptoms of AD are urgently needed. While there are drug products available to attempt to alleviate symptoms of Alzheimer's disease, such as memory and attention loss, so far no drug has been approved to alter the course of the disease.
  • Schizophrenia is a chronic mental disease that disturbs several cognitive functions, such as memory, thought, perception and volition.
  • Major symptoms include hallucinations (typically hearing voices), delusions, and disorganized thinking. Other symptoms include social withdrawal, 2 decreased emotional expression, and apathy. It affects approximately 0.5%-l% of the worldwide population.
  • 2017 there were an estimated 1.1 million new cases and in 2019 a total of 20 million cases globally.
  • Individuals aged 55 years and older will soon account for 25% or more of the total population of patients with schizophrenia worldwide.
  • the prevalence of schizophrenia in older adults set to double and reach 1.1 million people in the US by 2025.
  • Older patients with schizophrenia include individuals with an early onset that persists into later life and those with a late onset of this condition.
  • Older adults with schizophrenia have significant cognitive deficits in executive functioning, speed of processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning, and problem-solving (Daban C, et al. J Psychiatr Res. 2005 ;39: 391-8, Schappi L, et al.. Front Psychiatry. 2018;9:129) .
  • Differentiating between schizophrenia and Alzheimer disease with psychosis in older adults can be difficult (Radhakrishnan et al Advances in psychiatric treatment 2012, vol. 18, 144-153), It is interesting to note that older adults with schizophrenia and a high anticholinergic burden have a cognitive impairment profile consistent with that observed in Alzheimer dementia.
  • the causes of schizophrenia include genetic and environmental factors. Genetic factors include a variety of common and rare genetic variants. Serotonin (5-HT) receptors have been suggested to play key roles in psychosis, cognition, and mood via influence on neurotransmitters, synaptic integrity, and neural plasticity. Specifically, genetic evidence indicates that 5-HT1A, 5- HT2A, and 5-HT2C receptor single- nucleotide polymorphisms (SNPs) are related to psychotic symptoms, cognitive disturbances, and treatment response in schizophrenia (Sumiyoshi et al Adv Ther. 2008;25( 10): 1037- 1056.).
  • SNPs single- nucleotide polymorphisms
  • Autism or autism spectrum disorder is a complex neurodevelopmental condition characterized by persistent difficulties in social interactions and communication, as well as restricted interests and repetitive behaviors. ASD is typically diagnosed during the first three years of life and manifests in characteristic symptoms or behavioral traits (core symptoms). A diagnosis of ASD now includes several conditions that used to be diagnosed separately: autistic disorder, pervasive developmental disorder not otherwise specified (PDD-NOS), and Asperger syndrome. All of these conditions are now encompassed by the diagnostic criteria for autism spectrum disorder as set forth in the American Psychiatric Association's Diagnostic & Statistical Manual of Mental Disorders,
  • DSM-V Fifth Edition
  • individuals with autism may also experience co-occurring conditions such as depression, anxiety, insomnia or behavioral disorders (e.g. irritability, hyperactivity, aggression), intellectual disability, epilepsy, as well as non-neurological comorbidities, including blood hyperserotonemia, immune dysregulation, and GI dysfunction (e.g., chronic constipation, diarrhea, abdominal pain, and gastroesophageal reflux).

Variant genotyping of a combined Whole Genome and Whole Exome sequencing, was performed.
